Building an ogre bodyguard

I don't particuarly like the old bodyguard model and the ogre kingdoms bodies look like junk. I had an idea of using a plastic Nurgle Chaos Lord as a body to be mixed with a few ogre parts. Does anyone know if it'd be large enough?

I'd like to make someing close in size to the actual bodyguard figure but I don't have one to compare thinsg against for a sense of scale. Does anyone have models they can take a side by side picture of?
